Here is a full guide to General Election night 2017 - the key moments to look out for and when and where to see them.

What to watch:

BBC

David Dimbleby will be leading the coverage on BBC One and the BBC News Channel as the polls close, from 9.55pm to 7am on Thursday. This will be his 10th time at the helm of the BBC's coverage, joined by graphics whizz Jeremy Vine and reporters Emily Maitlis and Mishal Husain.

Huw Edwards will then take over until 10am on Friday, joined by Andrew Neil at 1pm. Neil will host the rest of the coverage on BBC Two until 4.30pm.

ITV

Tom Bradby will steer ITV's coverage through the night, starting at 9.55pm. He will be joined by the channel's Political Editor Robert Peston, former Labour MP and Strictly Come Dancing star Ed Balls and Evening Standard Editor and former Chancellor George Osborne.

Piers Morgan and Susanna Reid will take over with a special edition of Good Morning Britain from 6am-9.25am, after which an extended ITV news will run until 2pm.

Channel 4 is mixing comment with comedy for its alternative election night. From 9.45pm the stars of Gogglebox will be giving their views on the election, followed by news heavyweights Jeremy Paxman and Cathy Newman co-hosting with David Mitchell and Richard Osman.

The programme promises to combine serious coverage mixed with light relief until 6am.

Sky News

Veteran news editor Adam Boulton partners with Sophy Ridge to lead the election charge on Sky News, beginning at 9pm. They will be supported by live coverage from 300 constituencies.

Sky's results night will extend to Snapchat from 10pm with rolling coverage on the picture and video sharing platform.

First indication of results:

The result of a joint BBC, ITV and Sky exit poll will be released at 10pm - as soon as polling stations close.

The survey will be taken from 144 polling stations across Britain, asking voters at these stations to mark a mock ballot paper to show how they have voted.

Similar exit polls have correctly predicted who would take the keys to Number 10 in the last five elections, and in 2005 and 2010 came extremely close to predicting the exact number of seats.

Results to watch for (timings approximate)

By 12am

The three Sunderland constituencies - traditionally first to declare - should be in. All are safe Labour seats and all three should return women MPs, meaning that by this point in the night the House of Commons should be 100 per cent female.

1am

Nuneaton: The first marginal seat to declare. Marcus Jones (Con) is defending a majority of 4,882 and Labour needs a 5.4 per cent swing to win.

1.30am

Darlington: If the Tories win here in Labour's heartland of north-east England, they are on course for a very good night.

Wrexham: The first chance for the Tories to gain a seat from Labour in Wales.

2am

Bury North, Peterborough and Thurrock: Three Tory marginals are due to declare - all are key Labour targets.

Clwyd South: Can the Tories surge in Wales and grab this seat from Labour?

Hastings and Rye: The seat of Home Secretary Amber Rudd, which would fall to Labour on a 4.8 per cent swing.
